DAVID BUZZELL, OF CHARLESTOVN, MASSACHUSETTS.

BOOKING-CHAIR.

Specification of Letters Patent No. 22,486, dated January 4, 1859i.

To all whom tt `may concern:

Be it known that I, DAVID BUZZELL, of Charlestown, in the coun-tyofll/liddlesex and State of Massachusetts, have invented an ImprovedRecumbent Rocking-Chair; and do hereby declare that the same is fullydescribed and represented in the following specification and theaccompanying draw* ings, of which- Figure l, is a top view ot said chairas it appears preparatory to its being upholstered, the back beingthrown down into an inclined position. Fig. 2, is a side elevation oiEthe same the chair under such circumstances being exhibit-ed assupported on the floor by means of its caster or toot levers. Fig. 3, isa side view fot it as it appears when supported on its rockers, Fig. 4,is a longitudinal and central section ot it when its parts are inposition as shown in Fig. 3. Fig. 5, represents a longitudinal sectionof it with its bach elevated and its leg .rest brought into a verticalor nearly vert-ical position.

rThe chair .with which my invention or improvements are represented issuch as was patented by me on the 31st day of August, 1858, andrepresented in United States Patent No. 21,320.

In the above mentioned drawings, the seat frame of the chair isexhibited at A, as constructed of two leg portions, a, a, (each of whichhas two legs, o, 5,) connected by bars, c, c, and in manner to receiveand support the arm rests, d, (Z, which are stationary relatively to theback B., the seat C., and the leg rest, D. The said back, seat, and legrest are connected together and applied to the seat frame A, andoperated by mechanism all substantially as described in my said patent,in order that while the back is being turned downward into an inclinedor recumbent position, the leg rest may be turned upward and on itsjournals or supports, the positions of the said parts under suchcircumstances being as shown in Figsl and 2, of the accompanyingdrawings.

To the leg rest D, or levers, e, e, (making part of the same,) I applyan extension toot rest frame E, carrying a foot rest, F., which may beso applied to the said frame E, as either to be stationary relatively toit, or be capable of being turned or folded up or down in the ordinaryway.

The frame E of the foot rest is iitted to the leg rest levers in suchmanner as to be able to slide between them, either toward or away fromthe seat, the upper part of the said foot rest traine being hinged orjointed to two levers G, G, turning on fulcra f, f, extended from theinner -sides of the levers, e, e, respectively. The longer arms of thesaid levers Gr, G, pass respectively through staples g, g, (or theirequivalents) applied to the front cross bar of the .seat frame, the samebeing shown in the drawings. lVhile the leg rest is being elevated, thesaid levers rGr, G, acting in the staples, g, g, will be moved on theirfulcra so as to move the toot rest in a direction away from the seat andthus extend it in order to accommodate the said foot rest to theposition of the feet of a per-son 'as his legs are drawn up or movedtoward a horizontal position. As the movements of the leg rest arecontrolled by those of the bac-lt, it will be readily seen, that whilethe back is being moved forward from a recumbent to a vertical position,the leg rest will be depressed, and the toot rest be brought nearer tothe seat.

A foot or caster lever, H, is jointed to each leg of the seat frame soas to be capable of turning in a vertical plane, on a fulcrum, 7i, suchlevers being arranged as shown in the drawings. At or near the outer endof each ot the said levers, either a caster or a foot, i, may beaffixed. Furthermore, a rocker, l, is applied to each pair of tootlevers, on each side of the chair, that is to say, the said rocker, nearits front end turns on a pin or screw it', extending through it andbeing screwed into the front foot lever. Besides this, a similar pin orscrew, Z, extends through a slot, m, formed in the rocker as shown inFig. l, the said screw being screwed into the rear foot lever.Furthermore, there is placed between each pair of foot levers and itsrocker, a lifter lever, K, which is formed as shown in side view in Fig.6. At or near its front end the said lifter turns on a pin or fulcrum,a, extended from the rocker. The rear end ot each of the said lifterlevers is jointed to the lower toggle, L, of a pair of toggles, L, M.,there being two pairs of such toggles, and each pair having its uppertoggle, M, jointed tovv the seatframe so as to be capable otl swingingin a vertical plane. The two sets of toggles are connected together by ahandle shaft, 0, which extends :trom the joint of one pair to that ofthe other. Furthermore, at or near the middle of each lifter lever or t0a projection, p, therefrom, a connection bar or link 7, is jointed so asto be capable of swinging in a vertical plane. The lower end of the saidconnection bar is jointed to the rear arm of the front foot lever at 2f.Another conneetion bar, u, ointed at one end to the inner arm of therearmost foot lever is also jointed at its other end to the'middle partof the connection link, r.

Then the handle shaft, o, is in its lowest position, as shown in Fig. 4,the chair will be supported by its rockers resting on the floor, but ifthe handle shaft be moved upward into its highest position the chairwill be supported by its foot levers, whose feet will then be on theground or ioor underneath it. Therefore, by means of the two rockers andtheir two sets of foot levers arranged together and connected by liftinglevers or mechanism as specified, or any equivalent therefor, the chairmay be converted from a stationary reeumbent, to a rocking recumbentchair, or vice versa, at pleasure.

I do not claim an extension foot rest or one so applied to a chair as tobe capL ble of being moved toward or away from the `,seat of the chair,and whether such foot rest be sustained by cords and weights or not, assuch a foot rest 1s very old and has been 1n use many years. Nor do Iclaim a chair constructed as shown in the United States' Patent, No.19,352, but

I claiml. In combination with the chair stand or frame, the movable legrest and the sliding foot applied to such leg rest essentially7 asdescribed, a mechanism, by which, when the leg rest is moved or swungupon its fulcra or bearings, the sliding foot rest shall be moved onlits supports, either toward or away from the seat substantially asspecified.

2. I also claim the combination of the foot levers and the rockersapplied to the chair o-r seat frame, and so as to operate togethersubstantially as described.

3. I also claim the combination of the toggles, the lifting levers andtheir connections with the foot levers and rockers the same being forthe purpose of so operating the said rockers and levers as to cause thechair to be supported on the ground 0r floor, either by the two rockersor the four foot levers as set forth.

4. I also claim so combining a foot rest with a movable or turning legrest, that the former shall be movable relatively to the latter asspecified.

In testimony whereof I have hereunto set my signature.

DAVID BUZZELL.
